@ws1088 I'm sorry but I don't know what that is.

I'm not sure as you need @heybin for this but I don't believe that lcd.setRotation() is implimented yet in tis version of micropython.

@heybin Thanks. Is there a StickC branch for UIFLow_Code as well? I looked at https://github.com/m5stack/UIFlow-Code/blob/master/i2c_bus.py and PORTA is (21, 22) for M5Stack, not (32, 33) for M5StickC.

@oliv said in Battery life of M5StickC when it is powered OFF:

@lukasmaximus : I agree with @ws1088 . Battery fully charged, long press on power switch to switch off the M5StickC should not drain battery in 5 hours.

I measured a consumption of 1.92 mA when off, which is too high :(
See measurements: http://community.m5stack.com/topic/1162/getting-longer-battery-run-time/5

Today I did something different, I unplug every units from M5StickC and so far it still have battery when I tried to turn it on. After it is on, I turned it off immediately and will report out how long it will last. Sorry, I can only do these unscientific experiment :) I lack the knowledge and equipment to do otherwise.

@ws1088 said in Connecting Env Unit and RFID Unit via Grove Hub on M5StickC:

I use the following code to test:

from m5stack import * from m5ui import * from uiflow import * import i2c_bus setScreenColor(0x111111) devices = None scan = None i2c0 = i2c_bus.easyI2C(i2c_bus.PORTA, 0x68) devices = [] while True: scan = i2c0.scan() if devices != scan: lcd.clear() lcd.print(str(scan), 0, 0, 0xffffff) devices = scan wait_ms(2)

I can see the I2C addresses for the Env unit and RFID unit combinations when I plug them into the Grove Hub. I can plug the Env unit in to see addresses 92 and 118, then add RFID unit to see [40, 92, 118] etc.

So I am pretty clueless why the following will fail:

rfid0 = unit.get(unit.RFID, unit.PORTA) env1 = unit.get(unit.ENV, unit.PORTA)

Looks like I need to go to the source code and see what's going on...

are modules working ok on their own and you see issue when both connected?

The Api key is for connecting your stick c to the online version of uiflow (flow.m5stack.com) in the settings menu you can enter your apikey and switch from m5stack unit to stick c unit

The interesting thing is in USB mode you still get an apikey. I tried entering that key in the online version of UIFlow and it is not working...

It wont work because in USB mode the M5Stack has not connected over the wifi and so the online UIFlow cannot find it.
This is a bug or a feature of the upcoming WebUSB function coming soon.

Thanks, lets hope it is a feature for the online version of UIFlow instead of a bug :)

Congrats, good to know
